Joining County Data from API to Feature Service

EricSamson3 — Wed, 19 Feb 2020 22:09:31 GMT

I am working on a web application that calls to an API and grabs county data in a json format. I have a feature service that shows county boundaries. I want to join the json data from the api to the feature service by the county ID, once the api is called.

I am seeing some options on how to do this using the leaflet API package, any suggestions on how to get this accomplished with the ArcGIS API?

Thanks

Are you planning for this to display in a popup?

Yeah, essentially there is just one field I would like to join by the county ID layer which will contain a value. The feature service will then be colored by that value and the information will be available in a pop-up
